The skill position unit could use a booster shot considering none of the tailbacks are proven, the tight ends all have different shortcomings that could tip off Miami's playcalling, and the 53-man roster only features four receivers at the moment.

But that's what good coaching is for I guess. Insert the mantra for 2013 remind yourself that Joe Philbin and staff need to find a way to "Make It Work."

Comment: Tannehill has made nice strides during the preseason, producing a 98.6 passer rating in the four games he's played. He's clearly improved heading into his second season as a starter, but can Tannehill produce fourth-quarter victories? We'll soon find out. Moore is one of the more accomplished backups in the NFL, and Devlin is entering his third season with the team.

Comment: Miller and Thomas will share the backfield, and between those two the Dolphins SHOULD be able to produce big runs, and grind out tough yards. Miller's durability is a concern, and Thomas needs to improve his yards per carry average. This unit's ability to pass block remains a huge issue, and might impact the offense. Thigpen is a return specialist, and can be used as a slot receiver in a pinch. The Dolphins claimed Clutts off the waiver wire. He replaced Evan Rodriguez on Sunday, and will be used as a traditional fullback and core special teams player.

Comment: Quality depth remains an issue in this unit, and could become problematic if one of the front line receivers suffers an injury. Wallace, Hartline and Gibson make up a strong trio, and plenty will be put on their plate this season considering the offense lacks a proven tight end. Matthews has upside, but is still recovering from a knee scope. At the least the Dolphins will need to find some decent practice squad receivers, getting them ready for a possible callup.

Comment:Dustin Keller’s season-ending knee injury sends the Dolphins searching for a starter. For now Clay, an H-back who has started 16 games in that role, will get the bulk of the work. But he's not a traditional tight end. That means Sims or Egnew must elevate their level of contribution for this offense to threaten the middle of the field.

Comment: Pouncey, Incognito and Clabo are upper echelon players at their position, and Martin showed this preseason he has upside at left tackle. Jerry has been an adequate starter at right guard for two of the last three seasons, but the coaches need to find a way help him elevate his level of play. Jerry's a strong pass blocker, so at least the line won't be compromised from the inside. Samuda and Garner are the top backups. Yeatman, a converted tight end entering his third season with the Dolphins, and Thomas, a third-round pick being groomed as a right tackle, still need plenty of polishing.
